IWRL6432BOOST: Read ADC Data via SPI for IWRL6432 but SPI Pin is not working

Hello expert,

I am working with the IWRL6432 radar and would like to obtain raw data via SPI. I followed these instructions and was able to obtain the raw data. After a few successful attempts, I tried to start the transmission again and it didn't work.

I reflashed and reconfigured the board successfully, but SPI data transfer no longer works. To check, I connected the SPI pin from the radar to the oscilloscope and the CS and interrupt pins showed no signals.

Could it be that the SPI pin is broken or have you already had such a problem and can help me?

Hi,

That could be a possibility since the data capture was working previously. Can you run the SDK SPI driver example once and check?

You can also use Logic Analyzer to check the SPI clock first.

Regards

Hello,
Thank you for your answer, I was able to solve the problem. After the configuration, I still had to send the message “sensorStart 0 0 0 0” for the board to start measuring.
